Concrete “evidence” by itself would only convince a small minority of people at most that God exists and that we should follow him. Following Jesus does not become any easier with “evidence.” There are still many things that we must wrestle with and submit ourselves to God to, and evidence does not make it any easier to love your enemy, serve your neighbor, resist sexual temptation, etc.
That being said, here are three reasons why “more evidence” would not change most people’s perception about God.
1) There already is plenty of evidence.
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them.
For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
Every civilization in the history of the world has believed in some sort of the divine. The only ones that have not are ones in where the government forces it’s people not to (i.e. communist China and Russia). Even still, many people practice their faith “underground.”
Everyone believes in some sort of good and evil, is in some way amazed at the beauty of nature or the universe, and does not initially believe that our existence came from nothing (unless told by some “rational” scientists that we were created out of nothing).
Why? Because God has shown us glimpses of his greatness. And this is what we should expect from a loving God who wants a relationship with us.
2) God has shown himself to people in the past, and they still rejected him.
Though there are many, I think the best example of this in the Bible is when the Israelites were wondering the desert on the way to the promise land.
In Exodus 32 as Moses is meeting with God on Mount Sinai for forty days and nights, the Israelites become impatient.
When the people saw that Moses delayed to come down from the mountain, the people gathered themselves together to Aaron and said to him, “Up, make us gods who shall go before us. As for this Moses, the man who brought us up out of the land of Egypt, we do not know what has become of him.”
Aaron, Moses’ elder brother and high priest of all the Israelites, then has the Israelites melt down their gold, form a golden calf, and worship it.
This happened despite the fact that God had sent the plagues in Egypt while the Israelites were in captivity. Despite the fact that God parted the red sea before their very eyes. And despite the fact that God miraculously provided food for all of them every night while they slept (Exodus 16).
God gave them as much evidence as anyone would need to prove that he was real, yet many times throughout scripture we see how many rejected him.
These days, people will often say that they just need one miracle from God to know that he is real, yet the Israelites received at least one every single day (Manna provision in Exodus 16) and many still did not completely trust in him.
It’s easy to say you would believe in God and follow him if he gave you the most clear evidence of all, a miracle, because it is easier to say something than it is to do it. We see from the Israelites that knowing God exists without a single doubt does not make easier to deny our sinful nature.
3) “Evidence” does not make it any easier to serve, honor, and obey God.
As I said in the beginning, following Christ does not become any easier with “evidence.” Loving your enemy, serving your neighbor, and resisting sexual temptation aren’t easy things to do. Period.
Denying our sinful, selfish desires is difficult. We can see this firsthand with Adam and Eve.
Adam and Eve knew God. They were created by him and still disobeyed. They had more “evidence” of God’s existence than anyone who has ever lived, but that didn’t make living as he called them to live easy, and they only had one command!
They knew God and talked with God, yet all of that did not make them immune from actually having to live out what they knew.
With all of the talk about needing evidence, this last point is the one gets me the most. Living a life that honors God is deeper than any evidence can demonstrate. The reason being that once someone is convinced or learns of God’s existence, it means they must now live in a way to honor God.
For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.
In order to honor God we must put to death the deeds of the body. Deeds like lust, greed, and deceitfulness. And while these things alone are difficult to do, that is not all. As Jesus said:
If anyone would come after me, let him deny himself and take up his cross daily and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will save it.
We are called to serve like Jesus, love like Jesus, and die like Jesus. This means we are to put others desires before our own, help those in need, and love those around us.
Unfortunately, none of us are perfect and thus do not always honor God as we should. Thankfully, we have a savior in Jesus who forgives, loves, and redeems us if we ask him; but we must ask him.
For those waiting for more evidence, I’m not sure where you should look. Perhaps you could wait for the next scientific discovery that documents the vastness of our universe or the complexity of a mere ant, but evidence is probably not what is going to change your mind.
My suggestion? Ask God himself. He loves you enough to die for you, and will change your life if you let him.
And once your life is changed, you will have all of the evidence you’ll need.
